TO ALL WHOM IT MAY CONCERN: i A

Be it known that I, JOHN I-I. ELWARD, of Mendota, in the county of La Salle, and State of Illinois, have inventeda new and useful improvement in Devices for Fastening Ropes and Wires; and 'I do hereby declare that the following 4is a full, clear, and exact description of thel same, reference being had to the annexed draw ings, making part of this specification, in which- Figure 1 is a front elevation, and

Figure 2 is a longitudinal section.

The same letters are employed in both drawings in the indication of identical parts.

On the 9th day of July, A. D. 1867, e patent was issued to me on a device for holding ropes or wires. In the device set forth in that patent si. cam-lever is shown, pivoted to a. plate, one end of `which is intended to compress the rope or wire'against the faceof a. projection from the plate. The rope or wire, after passing between these parts, is carried over the ioug arm of the lever on which it rests, and by its own weight compresses the clasped portion between the cam and projection, thereby suspending the rope or wire. The device therein. shown is subject to the objection that two kinds of clamps mustbe constructed and employed where a rope is to be suspended across the space between two of. such clamps. This improvement is intended to provide for such ceses by a single clamp, which, being double-acting, may be used at either end of the rope, and it is in this that my improvement consists. It is, constructed as follows, viz:

bis a metallic plate, to be attached to a post, building, or other support. B is a. cam-lever pvoted to the plate at D. The long arm of the lever terminates with. a. rounded projection, C, over which the rope passes, 'between it andthe plate A. The short end ofthe lever is bifurcated, having on each side of the pivot rounded projections E andE. .Fisc projection from the plate A, intermediate between the vprojections E and E. The rope or wire, being carried overthe long n rmof the leverat C, may be carriedl between either of the projections E or E andthe projections F, as may be necessary to confine it, by the action of its own weight, bearing `upon the long-arm of the lever, and compressing it between the projections E or E and. F.

I do not desire rto limit my claim to the precise form of the parts here shown, nor to claim broadly the use of vthe comlever B 'and' projection F, as that is the object of my other patent hereinbefore mentioned. What I do claim ns myinvention, and desire to secure by Letters Patent, is-

A double-acting clamp for suspending ropes and wires, consisting of a. binrca-ted cam-lever, B, having the parts C, E, und E', and the intermediate projection F, arranged to operate substantially as described.

In testimony whereof I have signedpiy name to this specification in the presence of two subscribing witnesses.

` JOHN H. ELWARD.
